Version 3.4
What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

Near term (through tonight)
issued at 347 pm edt Mon jun 18 2018

Decreasing showers... Clouds and temperatures tonight...

high impact weather potential... None.

Pattern synopsis forecast... Main cold front currently extends from
pzq to acb... With surface ridging now poking into upper michigan
associated with a large area of high pressure over central canada.

Area of widespread showers from this morning has diminished to
lingering scattered mainly light showers for locations along and
south of the cold front where surface dwpts remain in the upper 60s
and lower 70s. Behind the cold front temps are holding into the
upper 60s to around 70 with dwpts falling thru the 60s as drier low
level air and subsidence begin to filter into the region.

Remaining scattered shower activity will continue to diminish from
north to south as the cold front continues to press thru the rest of
our cwa. Residual low clouds will follow suit across our northern
cwa... With some low clouds hanging around a bit longer across our
southern cwa. Temps will be noticeably cooler tonight vs. Last
night... With overnight lows cooling into the 50s for most of our cwa.

Short term (Tuesday through Thursday)
issued at 347 pm edt Mon jun 18 2018

Seasonal temperatures with a slight chance of precipitation...

high impact weather potential: none, fairly seasonal early summer
pattern across the great lakes.

Primary forecast concerns challenges: forecast concern will be
centered on chance for precipitation lifting north Tuesday and
Tuesday night.

Pattern synopsis forecast... A fairly non-dynamic pattern will be in
place across the great lakes and upper midwest during much of this
work week. A large area of high pressure settling over the upper
great lakes and northern plains to begin the work week will remain
nearly stationary through Thursday. However, a system organizing in
the central plains will try and lift north into the ohio valley and
nudge toward the SRN great lakes Tuesday night. Any pcpn chances
through the forecast period will be limited to the SRN portions of
the cwa. 850 7500mb qvector convergence associated with this
boundary lifting into the area, will push up across lower michigan
with a northward extent to a line between saginaw bay and manistee
Tuesday night. Additionally, model soundings and mstr progs show a
much drier and more stable airmass over the great lakes compared to
this past weekend (sfc dew pts in the 70s Sunday), with sfc dew pts
falling into the mid 50s Tuesday and upper 40s by midweek.

Overall based on model trends, will continue with current line of
thinking, with any pcpn moving northward into central lower michigan
being confined to the SRN most portions of the forecast area Tuesday
night and early Wednesday. Will only mention rain showers possible,
as stable mid lvl lapse rates and mid lvl drying greatly reduce the
change of convection.

Long term (Thursday night through Monday)
issued at 347 pm edt Mon jun 18 2018
a summer-like pattern is expected across the great lakes through
next weekend, with a largely stagnant upper level pattern and 850mb
temps around 13c helping generate afternoon temperatures in the
upper 70s and lower 80s. A storm system trying to organize over the
central plains midweek, will lift north into the ohio valley and
southern great lakes Friday and generate a round of showers and
storms over much of the CWA into early Saturday.

Aviation (for the 18z tafs through 18z Tuesday afternoon)
issued at 103 pm edt Mon jun 18 2018
residual showers will gradually diminish from NW to SE thru the
afternoon as a cold front presses southward thru northern lower
michigan. MVFR ifr conditions will slowly improve as showers come
to an end in response to building subsidence and dry air pushing
into our area in the wake of the cold front.VFR conditions are
expected for most of tonight and Tuesday as high pressure and
drier air continue to build into the region. N NW winds AOB 10 kts
this afternoon and tonight will become easterly on Tuesday.

Marine
Issued at 347 pm edt Mon jun 18 2018
winds and waves will remain below SCA criteria thru mid week as high
pressure gradually builds into northern michigan. Remaining showers
will come to an end this evening... With some decrease in cloud cover
as well.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
